House Oversight and Government Reform Chairman Jason Chaffetz strongly addressed Conway for her advertisement.

“That was wrong, wrong, wrong. It is wholly unacceptable. No, if, and’s or buts about it,” the chairman said to NBC News via a phone inquiry.

Chaffetz, a Utah Republican, and the committee’s ranking Democrat, Elijah Cummings of Maryland, are “working together to form and send a letter to the White House and Office of Government Ethics for a referral.” Earlier today, Cummings requested that the congressional panel review Conway’s violation.

“It should have never happened, and they better learn their lesson very quickly,” Chaffetz warned.

Chaffetz said he is unsure how this will be resolved or whether his committee will have a hearing looking into the matter, but this letter and referral is a good start.
